What a difference a year makes! This is the adorable Bronze-tailed Plumeleteer who, last year when I visited Rancho Naturalista in Costa Rica, seemed to be the most elusive of the hummers there, even more so than the Stripe-throated Hermit or the Green Hermit. This year, an immature male Plumeleteer, with wing, tail, and body pinfeathers still emerging, claimed a feeder near the Arabica Coffee tree next to the deck, riding herd (if that idiom can be used on such a tiny bird) on the area and chasing away any hummer that approached it. He maintained his vigilance all day every day we were there. He wasn’t always immediately visible to us as he sometimes perched in the bramble of vines beneath the deck but often as not, he perched in plain sight on a bare branch extending from the Arabica Coffee tree. He sat for such long periods, often preening to rid himself of the itchy sheaths encasing the emerging feathers, that a wing and tail stretch must have felt really good. One of the interesting things about this bird is the color of his feet. Mature Plumeleteers have bright red feet. This immature bird has rosy toes, not yet having turned a brilliant red.
